Abstract: Network devices add annotation information to network packets as they travel through the network devices. The network devices may be switches, routers, bridges, hubs, or any other network device. The annotation information may be information specific to the network devices, as opposed to simply the kinds of information available at application servers that receive the network packets. As just a few examples, the annotation information may include switch buffer levels, routing delay, routing parameters affecting the packet, switch identifiers, power consumption, and heat, moisture, or other environmental data.

Abstract: Disclosed are various embodiments that relate to a network switch. The network switch obtains a network state metric, the network state metric quantifying a network traffic congestion associated with a switch. The network switch identifies a synchronous time stamp associated with the network state metric and generates an network state reporting message, the network state reporting message comprising the network state metric and the synchronous time stamp. The network state reporting message may be transmitted to a monitoring system.

Abstract: Network devices facilitate flow management through packet marking. The network devices may be switches, routers, bridges, hubs, or any other network device. The packet marking may include analyzing received packets to determine when the received packets meet a marking criterion, and then applying a configurable marking function to mark the packets in a particular way. The marking capability may facilitate deadline aware end-to-end flow management, as one specific example. More generally, the marking capability may facilitate traffic management actions such as visibility actions and flow management actions.

Abstract: A device for performing congestion detection and management at a node of a network may include a congestion management module to monitor an arrival and a departure rate of data packets associated with a queue, a queue size, or a rate of change of the queue size. The congestion management module may identify the queue as a congested queue by one of determining that the arrival rate of the data packets associated with the queue is larger than the departure rate of the data packets associated with the queue, the queue size is larger than a first threshold, or the rate of change of the queue size is larger than a second threshold. The congestion management module may identify the congested queue as a congestion root by determining that the congested queue is not affected by a flow-control signal. A queue buffer temporarily stores data packets associated with the queue.

Abstract: A method for diagnosing performance of a network switch device includes a processor monitoring data generated by a sensor associated with a network switch device, the data related to states or attributes of the network switch device. The processor detects a determined condition in the operation of the network switch device related to the state or attribute. The processor generates an event trigger in response to detecting the determined condition and executes a forensic command in response to the event trigger. Executing the command includes sending information relevant to the determined condition for aggregation in computer storage and for analysis.

Abstract: In various embodiments, a system includes a switch comprising a resource that is shared between multiple objects. The switch comprises circuitry that determines a congestion metric for the switch in response to an amount of used of the resource by the objects. The circuitry determines a feedback parameter that is responsive to the congestion metric. The circuitry generates a congestion notification message that comprises a congestion feedback value responsive to the feedback parameter. In further embodiments, a system includes a switch that processes data for a first data link layer access network. The switch includes circuitry that identifies whether a received packet originated from a source device that shares the same network layer access layer as the switch. If the source device shares the same network layer access network as the switch, the circuitry generates a congestion notification message comprising a congestion feedback value for the switch.

Abstract: Processing techniques in a network switch help reduce latency in the delivery of data packets to a recipient. The processing techniques include internal cut-through. The internal cut-through may bypass input port buffers by directly forwarding packet data that has been received to an output port. At the output port, the packet data is buffered for processing and communication out of the switch.
